木薯在我国作为生物质能源、工业淀粉原料和潜在的粮食资源是热区最重要的经济作物之一。由于木薯遗传高度杂合和有性子代严重分离等不利因素导致育种周期长,育种进展缓慢。针对木薯育种面临的挑战,现提出综合育种的对策,并详细阐述木薯综合育种所需条件和流程以及发展前景,为缩短木薯育种年限和提高育种效率提供新思路。
Cassava is one of the most important economic crops in hot area in our country as biomass energy, industrial starch material and potential food resource. Due to the high genetic heterogeneity of cassava and the serious segregation of sexual offspring and other unfavorable factors lead to long breeding cycle, breeding progress is slow. In response to the challenges faced by cassava breeding, the countermeasures for comprehensive breeding are put forward. The conditions and process for comprehensive cassava breeding and the prospects for its development are expounded in detail. This will provide new ideas for shortening the breeding life of cassava and improving its breeding efficiency.
